VEHICLE-srRING..4

To all whom t may concern:

Be it known that I, JAMES MAUDSLAY SANDERS, a subject of the Kingof England, residing at Keynsham, near Bristol, in England, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a speciication.

Y This invention relates to springs for use on road vehicles and comprlses a casing working on a pivot provided for the spring between the ends of the spring while the end of the spring remote from the wheel axle lies between a pair of buffer springs one on each side of the spring and carried by a link pivoted to the frame, said casing inclosing the spring and adapted to serve as'an oil bath.

In the accompanying drawings Figure l is a central vertical section showing a construction of this invention; p

Figs. la and 1b showing details;

Fig. 2 is a horizontal section of the same, while Fig. 3 is a cross-section through the pivot on an enlarged scale.

In the construction shown in Fig. 1, the spring is shown at A, being mounted on a pivot A2 carried by a suitable part of the frame A2. The complete spring is inelosed in a casing B, which is rigid and of any desired cross-section, being, if necessary, circular, the end B2 being attached to the axle in any suitable Way or as shown in Fig. la in elevation and Fig. 1* in plan. The forward end of the spring A lies between a buer spring C interposed between the spring and the casing and a buier spring C2 interposed between the spring and the end of a link C3. The link C2 also carries the spring C2 and is slung from the pivot C2L and passes through the top of the casing. The forward end of the casing is inclosed by a plate B2 secured in any suitable manner, and the casing is provided with an oil cup or the equivalent at D so that lubricant can be easily admitted.

The spring casing is pivoted to the frame and the pivot may be located at any suitable point. In the instance illustrated the pivot of the casing is coincident with the pivot or trunnion A2 of the spring, and it may be Jformed with bosses B5 which take bearings also on the pivot A2 of the spring.

Preferably between the clip Y on the center of the spring and the pivot A2 is inter posed an eccentric sleeve E by the rotation i l Specification of Letters Patent.

of which the spring is raised or lowered slightly so that the height of the frame from the ground may be adjusted. This sleeve may be provided withserrations as shown at E2 locked by pins E3 carried by the spring clip Y, the whole being retained by a nut Ef.

Preferably the shape ofthe casing is as simple as possible with a view to simplicity and cheapness of manufacture, and in cases where the large end of the casing can be made circular the end plate B4 may screw into the casing. In other constructions it may be bolted or attached in any other convenient manner.

The invention can be applied to axles which are not driven, such as the Jfront axles of a motor vehicle.

In assembling, the cover B4 is removed and the spring fitted with its clip and the eccentric sleeve E are inserted through the large end of its casing. The pivot A2 can then be inserted in the eccentric Sleeve E and the nut E5 can then be screwed up through the aperture exposed when the cap Fr1 is remove l/Vhat I claim as my invention and desire to secure by Letters Patent is 1. In a vehicle, a spring, a pivot connecting said spring to the vehicle frame, a casing surrounding said spring, a link pivoted to the frame and engaging the spring and the casing at one end and a wheel axle attached to the other end of said casing.

2. In a vehicle, a spring, a pivot intermediate the ends of said spring and connecting said spring to the vehicle frame, a casing surrounding said spring, a link pivoted to the frame and passing through one end of the spring and the casing, springs upon said link and a wheel axle attached to the casing at the end remote from the link.

3. In a vehicle, a spring, an eccentric bushing connected thereto, apivot passing through said bushing and connectin said bushing to the vehicle frame, an oiI-tight casing surrounding said spring, a link pivoted to the frame and engaging the spring and the casing at one end and a wheel axle attached to the other end of said casing.

4:. In a vehicle, a spring, an eccentric bushing connected thereto, a pivot passing throng said bushing and connectin said bushing to the vehicle frame, an oitight casing surrounding said spring, a link pivoted to the frame and passing through one end of the spring and the casing, buder Springs upon sail link and a Wheel axleglttached to theee'sing attheend remote from the linkj" 5.
